Despite her repeated insistence that she won’t be a candidate, Warren supporters aren’t giving up. She is viewed by many in the progressive wing of her party as an alternative to Hillary Clinton, and President Bill Clinton’s, economic policies concerning issues such as deregulation and the couple’s ties to Wall Street, according to The Hill.

While Hillary Clinton has not declared her intentions, it is widely believed she plans to seek the Democratic nomination.

“Your ideas and the ideas of Bernie Sanders continue to be brought to the American people and you should join together to run for the Democratic nomination,” retired IBM employee Ray Donaldson told her at The New Populism Conference on Capitol Hill, according to U.S. News & World Report.

Last fall, Warren, along with all of her female Democratic colleagues in the Senate, signed a letter of support for a Clinton White House bid, according to The Hill, though Warren, Independent Vermont Sen. Bernie Sanders and Democratic Sen. Sherrod Brown of Ohio have called for Democrats’ to move left.

"During the financial crisis, I would say the single issue we've pushed the hardest on was — in return for the tens of billions of dollars that was shoveled in for these biggest financial institutions — a little accountability," Warren told the crowd. "What we got — and I want to be clear and this was under both administrations — was nothing, nothing and nothing out of that."
